AttiCal Insulation and Rodents

AttiCal Insulation and Rodents holds a perfect 5.0-star rating across 22 verified reviews, reflecting consistent quality in attic insulation, crawl space cleaning, and rodent exclusion services. Based in San Francisco, the company operates as Attical Inc. #1126472 and was officially founded in 2011. Their service area includes Fremont, Santa Cruz, and San Jose, where they handle residential insulation installation, rodent prevention, and indoor air quality improvements. The bilingual team communicates in English and Spanish, serving homeowners throughout the Bay Area.

What distinguishes AttiCal is their integrated approach to attic and crawl space remediation. Rather than treating insulation, rodent control, and air quality as separate issues, their technicians assess how each system impacts the others. The company offers full-service solutions ranging from deep attic cleaning and contaminated insulation replacement to HVAC system replacement and preventive rodent exclusion. This bundled capability allows homeowners to address multiple concerns through a single contractor rather than coordinating separate specialists.

Reviewers consistently mention specific technicians who delivered exceptional service. Apollo Chen praised David and Adrien for maintaining frequent, efficient communication throughout his crawlspace project, noting they identified issues that three other contractors missed while still providing the most competitive quote. Aide Varela described how Angel S. performed a thorough attic inspection, showing her exactly where rodents were entering, details she would never have noticed. The crew arrived on time, sealed all entry points, replaced contaminated insulation, and left the workspace cleaner than they found it.
